Hi, found these "non-sport" trading cards on the internets. If you scroll most of the way down there are military ones with a variety of uniforms from different countries during the 19th century.

You're looking for: N224 KINNEY MILITARY UNIFORM CARDS

They are all in full colour but are quite small!

Neat link.  Lots of other stuff buried among the various actress cards.  Check out "Ocean and River Steamers":

"Naval Vessels of the World" is also cool:

And check out the "Cards for Sale" sections for images of more naval vessels and uniforms. 

Again, great find!
